Formalized encoding method of action description natural text

The invention discloses a formalized encoding method for an action description natural text, which comprises the following steps of: (1) reading the action description natural text, dividing the action description natural text into sentences, and storing the sentences into a sentence set L; (2) taking any sentence li from L, performing word segmentation to obtain a word set W, and performing part-of-speech tagging to obtain a part-of-speech set P; (3) based on W and P, carrying out dependency syntactic analysis to obtain a dependency relationship set Rel; (4) based on Rel, extracting main components of the sentence li, and storing the main components into a component triple set E; (5) traversing E, and if part description or transformation description of the component triad does not have amatching result in the dictionary, changing the description into closest description of the matching result in the dictionary; (6) based on a dictionary matching method, carrying out formalized coding on each component tripl
